METHOD OF CONSTRUCTING CONCRETE BUILDINGS.

To all whom it may concern:

Be it known that we, VILLIA'M H. HAL- ,YERSON, FIN on WILCUOK, andHERBERT TREI- 0111a,, citizens of the United States, residing at Merced,county of Merced, State of California, have invented certain new anduseful Improvements in Methods of Constructing Concrete Buildings; andwe do declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings and to thecharacters of reference marked thereon. which form a part of thisapplication. a

This invention relates to improvements in a method of constructingconcrete buildings and is particularly adaptable for buildings usingreinforced concrete. I

The principal object of our invention is to devise a method ofconstructing the walls of such buildings in a quick and inexpensivemanner, and without the need of setting up vertical wooden forms inwhich to pour the concrete. By using our improved method, the outside ofthe walls may be smoothed or finished in any desired manner just as soonas the concrete is poured, while the interior surfaces of the walls willnaturally be fairly smooth and without the ridges and otherproturberances so common to walls poured into a rough-lumber form ormold. The advantages over the present form of construction. we gain byutilizing the floor of the building-which is laid prior to the wallsbeing formed, this being common practice-as a base or bottom of a moldon which to pour the concrete for the walls. The only form thusnecessary is an edging of boards laid on the floor, having a height thedesired thickness of the wall.

When firmly set, the wall sections are merely hoisted into place ontheir foundation, the abutting edges and corners filled with cement, andif the building is to be more than one story in height, the floor abovemay then be laid, and the 'wallsfor that.

story poured thereon.

The foregoing and other objects, we accomplish in a simple and easilyapplied manner, as will be evident from a perusal of the followingspecification' On the drawings which illustrate our improved method,similar characters of reference indicate corresponding parts in the several views. i

View showing a wall poured on the floor before being raised to position.

Fig. 2 1s a similar View showing end-Wall sections poured on top of theside Walls.

Fig. 3 1s a fragmentary perspective endview showing a side and end'wallsection raised to a vertical position.

Fig. 4 is a fragmentary cross section through the floor and foundationof the building, showing a wall section being raised to a verticalposition, and showing the same hinged to the floor along one edge.

Referring now more particularly to the numerals of reference on thedraw1ngs,'the

numeral 1 denotes the foundation of the building, 2 denoting one sideand 3 one end thereof. To this foundation are secured the usual floorbeams or stringers 4 on which is laid the flooring 5 which is level withthe top of the side foundation portion 2. On the floor We preferablystretch a layer of building paper 6 and then temporarily secure theretoan edging of boards 7 to outline the size of the wall 8, these boardshaving a height equal to the desired thickness of the wall.

In doing this, two methods may be fol lowed: The space intended for thewindows may be outlined by a form, or the window tween the sections andoverlap as at 10 only in that portion of the height of the wall where itis known the window will not be placed. When the boards 7 and theramforcing irons are laid in place, the concrete 11 is poured thusforming the side Wall sections 12. One edge of each such section liesimmediately adjacent the cor-responding foundation 2 and is hinged tothe floor by suitable hinges 13. l/Vhen the concrete is firmly set, somewet cement 14 is placed on the foundation, the edging is removed, and

each section then raised into place thereon by any suitable device, suchas a block and-tackle, etc. Directly after the concrete is poured, theupper surface of the same may be smoothed or otherwise finished off inpoured into rough wooden molds, on ac any desired manner, so that whenraised, the outer surface of the wall will need no further work donethereon. The inner surface, which is that next to the building paperlaid on the floor, will also be free from the roughness and defectscommon with concrete count of the smooth surface of the paper, and thissurface when raised will therefore s need only one coat of plaster toplace the same in a finished condition. When these side or lower wallsectlons are somewhat set, a layer of'building paper may be laidthereon, and the shape and size of the end walls 15 outlined 'thereon bymolding 16 and the concrete therefor poured in the same manner aspreviously described for the side them to the level of the top of theside walls when the same are lying on the floor The reinforcing irons inboth the side and end walls preferably project somewhat at the ends ofthe walls as shown at 17 in Fig. 3 so that when raised into position,and a small form erected at the corners, and concrete poured thereinto,a bonding means will be had forthis concrete. Also when the walls areraised, forms are erected :bove and below the'space for the windows ifthe walls are built by the sectional method, and concrete is pouredtherein to fill in the space between the sections.

From the foregoing description it will be readily seen that we haveproduced such a device as substantially fulfils the object of theinvention as set forth herein.

While this specification sets fortln in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spiritforming the walls on the floor of the buildmg, and when set, raisingthem into posi tion, one edge of each wall being in alinement with thefoundation of the building on which the wall is to rest.

2. The method of constructing the walls of reinforced concrete buildingsconsisting of forming the walls on the floor of vthe building by usingthe floor as one side of the mold and by then limiting the size of eachwall by an edging of planking temporarily secured to the fioor, theheight of such edging being the thickness of the Wall.

3. The method of constructing the walls of concrete buildings consistingof forming the side walls in vertical sections in a horizontal positionon the floor of thebuilding, placing a layer of building paper on suchwall sections, and forming the end wall sections thereon, whereby whenset the .end walls may first be raised to position on their respectivefoundations, and the side walls then similarly raised, the foundationsfor the end walls being correspondingly higher than those for thesidewalls.

4. The method of constructing the walls of concrete buildings consistingof utilizing the floor of the building as one side of the mold for thewalls and pouring the concrete thereon to a predetermined size andthickness, there being a layer of waterproof paper between the concreteand the floor whereby the concrete may not adhere thereto. y Intestimony whereof we aflix our slgnatures.,
